CULTIVATOR.

Specification of Letters Patent.

Application filed May 20, 1911.

To all whom it may concern:

Be it known that 1, WILLIAM J. BURROWS, a citizen of the United States,residing at De Lay, in the county of Lafayette and State of Mississippi,have invented certain new and useful Improvements in Cultivators, ofwhich the following is a specification, reference being had to theaccompanying drawlngs.

This invention relates to improvements in cultivators and has for itsobject to provide a cultivator of that type wherein the soil at oppositesides of a plant row and the soil upon one side of adjacent plant rowsis simultaneously plowed or disturbed.

A further object of the invention is to provide means for transverselyadjusting the plow beams in accordance with the width of the plant row.

Still another object of my invention is to provide adjustable shieldplates for preventing the earth being thrown by the plows or shovelsupon the plants.

With the above and other objects in view, the invention consists of thenovel features of construction, combination and arrangement of partshereinafter fully described and claimed, and illustrated in theaccompanying drawings, in which Figure 1 is a top plan view of acultivator embodying my improvements; Fig. .2 is a section taken on theline 22 of Fig. 1; and Fig. 3 is an enlarged transverse section taken onthe line 33 of Fig. 1.

Referring in detail to the drawing 5 designates the central longitudinalbeam of a substantially V-shaped frame, the side beams 6 being rigidlysecured to said beam at their forward ends and diverging rearwardlytherefrom. The bolt 7 which secures the beams 5 and 6 together alsopasses through the forward ends of the plow or shovel beams 8. Theseshovel beams are formed of tempered steel, and adjacent to their securedends they are reduced in thickness so as to render the same somewhatresilient. The beams 8 extend longitudinally between the central framebeam 5 and the side beam 6 and intermediate of their ends the beams 8are provided with suitable openings to receive a transverse rod 9 whichis also disposed through alined openings in the frame beams. One end ofsaid rod is headed while a nut 10 is threaded upon the other endthereof.

The rear ends of the shovel beams 8 are curved downwardly as indicatedat 8 and have arranged upon their lower ends suitable shovels or plows10 of any preferred form. These curved portions of the shovel beams arealso provided with openings 11 through which the transverse rod 12 isloosely disposed, said rod also extending through the openings 13 in theame beams 5 and 6. The rod 12 has centrally formed thereon a cylindricalenlargement 14 which is disposed through the central framebeam 5 and isprovided with screw threads upon each of its ends. The rod 12 is alsoprovided with additional cylindrical enlargements 15 adjacent to eachend thereof, the opposite ends of the same being provided with right andleft hand screw threads respectively, as indicated at 16. The openingsin the curved rear ends 8 of the shovel beams 8 are sufficiently largeto loosely receive the enlargements 15 and upon the threaded endsthereof the nuts 17 are engaged and are adapted tobe adjusted intocontact with the opposite faces of the beam 8. It will therefore be seenthat owing to the resilient nature of the beams 8, by simply adjustingthe nuts 17 upon the threaded ends of the enlargements 15, the plows orshovels 10 may be transversely adjusted with relation to the framewhereby they can be properly positioned upon opposite sides of the plantrow. The nuts 17 are formed with the short sleeves 17 which are notprovided with threads so that they can move freely upon the enlargements16 as the nuts are adjusted.

Shield plates 18 are arranged on opposite sides of the beams 5, and eachof said plates has formed on one end thereof a shank 19 which isprovided with an opening to loosely receive the central cylindricalenlargement 14 of the rod 12. These shield plates extend longitudinallyupon opposite sides of the plant row and closely adjacent to the plants.Nuts 20 are threaded upon the ends of the enlargements 14 whereby theshield plates may be transversely adjusted to dispose the same withrelation to the plows or shovels 10 and in accordance with the width ofthe plant row. These shield plates effectually prevent the earth beingthrown by the shovels upon the small plants which have not yet attainedtheir full growth and would thus be killed.

To the rear ends of the diverging frame beams 6, the shovels 21 arerigidly secured. These shovels are adapted to be disposed upon one sideof adjacent plant rows and are of such form that the earth or soil isthrown outwardly or away from the plants. The rear ends of the framebars are con nected by means of the transverse rod 22. A nut 23 isthreaded on the end of said rod to retain the same in said beams andrigidly connect and brace said beams.

The openings in the frame beams which receive the rod 12 are of courseof sufficient diameter to allow the enlargements of said rod to bereadily passed therethrough. After positioning the rod, suitable sleevesor bushings 23 are adapted to be inserted into the openings in the sidebeams 6, and nuts 24 are then threaded on the end of the rod 12 toseoure the same in the beams. To the rear end of the central frame beam5 suitable handle bars 25 are fixed so that the cultivator may bereadily guided or directed by the operator.

From the foregoing it is believed that the construction and operation ofthe invention will be fully understood without requiring any furtherdescription.

The cultivator is of comparatively simple construction, and as theforward plows or shovels and the shield plates may be easily and quicklyadjusted, the machine can be adapted for use under varying conditions.Owing to the simplicity of construction of the various parts, thecultivator is also very strong and durable in practical use and may beeasily and quickly assembled or disassembled for the purpose of repair.

While I have shown and described the various preferred forms of theparts, it will be understood that the elements of construc tion may begreatly modified within the scope of the claim without departing fromthe essential feature or sacrificing any of the advantages of theinvention.

Having thus described the invention what is claimed is In a cultivator,the combination With a frame, of longitudinally disposed plow beamsreduced in thickness at one of their ends and fixed to said frame, saidplow beams being resiliently movable transversely of the frame andhaving plows arranged upon their rear ends, a transverse rod mounted inthe frame and having spaced cylindrical enlargements, the rear ends, ofsaid plow beams being loosely disposed on said enlargements, saidenlargements of the rod being reversely screw threaded upon oppositesides of the beams, and nuts adjustable upon said threaded enlargementsof the rod to bear against the opposite faces of the plow beams and movethe same transversely with relation to each other and to securely clampsaid beams in their adjusted positions.

Intestimony whereof I hereunto afiix my signature in the presence of twoWitnesses. WILLIAM J. BURROWS. Witnesses:
